CLOSET BEND Filed Jan. 10. 1928 INVENTOR MJZecZloii ATTORNEY Patented Oct. 29, 1929 I um'rao stares oscoon M. REDLON, or BATH, MAINE CLOSET BEND Application filed. January 10, 1928. Serial No. 245,719.

My invention relates to a fitting termed a closet bend, and which is used in practice to connect a water closet bowl with the waste or soil pipe.

The general object of my invention is to provide a closet bend with a non-siphon inlet on either or both sides, whereby the water coming from that end which connects with the closet will not cause siphoning in other fixtures connected with the inlet, such as, for example, a bath tub or wash bowl, or other lavatory fixture.

The nature of my invention and its distinguishing features and advantages will more more clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a side elevation of a closet bend embodying my invention provided with a novel non-siphon inlet at one side which is given for the purpose of illustration;

Figure 2 is a longitudinal section taken on the line 22 of Figure 1 Figure 3 is a transverse section as indicated by the line 3.3 of Figure 1; and

Figure 4 is a cross section as indicated by the line 1- 1 of Figure 2, showing the enlargement of the inner end of the non-siphon side inlet.

In carrying out my invention in accord- Y-inlet or non-siphon inlet,.the numeral 10 indicates a pipe element which in practice is made of castiron adapted to connect with the soil pipe, and having a suitable connecting end 11. g

An elbow 12 having an inlet 14 of lead is seated in the flange 13 of the elbow 12, there being employed packing or calking material 15 extending about the connecting end of the lead inlet 14 between same and the flaring portion of the flange 13. The lead inlet 14 connects in practice with the closet bend by any suitable means (not shown).

A side inlet 16 is employed and leads into the soil pipe 10 adjacent to the elbow 12 of the ance with the illustrated example showing the I closetbend. The side inlet 16 is in the nature of a Y-connection inits relation to the'soil pipe connecting member 10. I

It is to be noted that the inner end of the side inlet 16 which connects in practice with any adjacent fixture, such as awash bowl or bathtub, is formed substantially square, that is to say, the sides are flattened and merge into the soil pipe connecting member 10 at one end adjacent to the elbow 12 receiving the water from the closet pipe connecting member 14,

which asstated is of lead. The-result; of squaring and flattening the sides of theinner end of the side inlet 16 gives an enlargement of said inner end beyond the capacity of the outer or inlet end 17 of the side or Y-inlet, so that the water flowing from the lead inlet 14 and through the elbow 12 cannot completely cover or produce suction in the side inlet 16.

As a consequence there can be no siphoning;.

action in the inlet 16 to siphon the wash bowl, bathtub, orthe like. I

In the side inlet or Y-inlet 16 advantageously is formed an inwardly directed flange 18 presenting a bore 19 pronouncedly of less ca-; pacity than the inner end of the inlet 16 having the flattened sides 20, thearrangement serving to carry out the function of the en larged inner end of inlet 16 having the flattened sides 20 for the "final purpose of pre-;. venting siphoning. I

I would state furthermore that while the illustrated example constitutes a practical embodiment of my invention, I do not limit my- I self strictly to the exact details herein illus-1 trated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims. V

I claim: 1. A closet bend as characterized, including a tubular member adapted at one end forconnection with a soil pipe, an inlet member adapted to be connected with a closet bowl,

and a side inlet leading into said soil pipe con-11.3.

necting element, the sides of said last mentioned member being flattened and affording a capacity beyond the said inlet member atits inner end to prevent water from said tubular member completely covering the inner end of.

the side element to prevent a siphoning action r on said side inlet.

' 2. A closet bend as characterized, including a tubular member adapted at one end for connection with a soil pipe, an inlet member at one end adapted for connection with a v closet 'bowl, said inlet member beingconnected with said tubular member by an elbow, and a side inlet leading into said tubular memher and having flattened sides merging into said tubular member at one end adjacent to the said elbow.

3. A closet bend, comprising a soil pipe connecting'member having at one end an el- 1 bow to which is'secured a pipe for connection with a closetboWl, and provided at the same end with an inlet for connection with a wash bowl or the like, the inlet standing at an acute angle to the member and opening into the same adjacent the elbow; the said inlet having the inlet.

its end opening into the member substantially square and provided adjacent the square and i on its inner face with an annular inwardly projecting flange restricting the passage of Signed at Bath in the county of Sagadahoc I and State of Maine this 7th day of January A.
